2.3.1.20 additional information TAG biosynthesis and metabolic engineering of soybean oil with appropriate DGATs. GmDGAT1A-transgenic hairy roots synthesize more 18:3-triacylglycerols. Overexpression of GmDGAT1A in Arabidopsis thaliana seeds enhances the TAG production, GmDGAT1A enhances 18:3-TAG and reduces 20:1-TAG contents in rod1 mutant seeds Glycine max
2.3.1.20 additional information TAG biosynthesis and metabolic engineering of soybean oil with appropriate DGATs. GmDGAT2D-transgenic hairy roots synthesize more linoleoyl- or oleoyl-triacylglycerols. Overexpression of GmDGAT2D in Arabidopsis thaliana seeds enhances the TAG production, GmDGAT2D promotes linoleoyl-TAG in wild-type but enhances oleoyl-TAG production in rod1 mutant seeds Glycine max
